Specific embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by specific embodiment.
Embodiment 1
As shown in figure 1, a kind of machine-roomless lift steel cable slot disengaging detection method, comprise the following steps：
Every steel wire rope 5 in using is bent respectively and is pressed in grooving 2, detect the pressure value to grooving 2 for the steel wire rope 5；
Pressure value is contrasted with pressure value set in advance, is judged the whether de- groove of steel wire rope 5.
The current state of surveyed steel wire rope 5 by being contrasted between actual value and preset value, is judged by comparing result,
Can determine whether to locate whether steel wire rope 5 currently takes off groove, judge whether further to be safeguarded according to test result, to guarantee elevator
The safety using.
The pressure data that in grooving 2, steel wire rope 5 produces is detected by pressure transducer, the pressure data recording is converted into
Digital signal passes to data processing unit, completes pressure value contrast by data processing unit.
Pressure transducer detects analogue signal, is judged by data processing unit after amplifying through signal, defeated after judgement
Go out corresponding digital signal, digital signal is passed to elevator control panel.
Wherein, by the status data of each grooving 2, layout becomes the binary number of several bytes to data processing unit in order
Value, and it is transferred to elevator control panel, wherein, every steel wire rope 5 state takies two positions, is 00 when normal, is 01, takes off when loosening
It is 10 during groove.As elevator has eight steel wire ropes 5, the data sending during steel wire rope 5 normal condition is 00 00 00 00 00 00
00 00；When steel cable 5 loosens, send steel wire rope 5 to take off groove anticipation signal data is 00 00 00 00 00 00 00
01；When steel cable 5 takes off groove, send steel wire rope 5 to take off groove signal data is 00 00 00 00 00 00 00 10.
Embodiment 2
As shown in Fig. 2 a kind of machine-roomless lift steel cable slot disengaging detection means, including plate-shaped detection main body 1, detect
The edge of main body 1 is provided with multiple open horizontal grooving 2 outwardly, and grooving 2 is vertically arranged；
The bottom of each grooving 2 is equipped with pressure transducer, and pressure transducer is connected with data processing module, data processing
Module is connected with elevator control panel.
During use, in grooving 2, steel wire rope 5 is to the pressure sensing utensil of grooving 2 bottom by certain for steel wire rope 5 mode
Pressure, the pressure value that pressure transducer Real-time Collection steel wire rope 5 produces, the signal collecting is conveyed to data by pressure transducer
The signal structure module of processing module, presets corresponding pressure value in data processing module, by data processing module to pre-
The pressure value first setting and actual measured value are contrasted, and judge actual pressure value whether in the range of presetting, and judge
After the completion of, digital signal is sent by signal emission module, elevator control panel receives digital signal, is completed down by elevator control panel
One step manipulation, such as takes the modes such as sound and light alarm, numerical monitor to be reported an error.
Detection main body 1 is provided with connecting rod 3.This detection means is installed to when using between many steel wire ropes 5 of elevator, because
This, arrange corresponding connecting rod 3 thereon for being fixedly connected to detection main body 1, setting peace on connecting the main body pressed
Dress plate, installing plate is provided with installing hole, thus can achieve being detachably connected, beneficial to the maintenance and repair in later stage of detection means.
Elevator control panel is provided with alarm device.Alarm device is audible-visual annunciator.Generally, when the steel wire of elevator
When the phenomenon of de- groove in rope 5, in order to avoid security incident occurs, should stop immediately elevator is continuing with, therefore, install
Audible-visual annunciator, can send sound and light alarm signal, can more effectively remind monitoring personnel.
In conjunction with the embodiments 1 and embodiment 2, the operation principle of this detection means is as follows：
A. elevator wire rope 5 bending certain angle is attached in grooving 2, and grooving 2 can bear the pressure from steel wire rope 5, this
When grooving 2 pressure sensing cell (pressure transducer) pressure data of corresponding steel wire rope 5 can be detected, pressure data is amplified
It is transferred to data processing unit (data processing module).
B. after data processing unit receives the pressure data of each grooving 2, by each grooving 2 pressure data with set in advance
Good data is compared judgement, if finding, certain pressure data is abnormal, can export corresponding digital signal to elevator controlling
Plate, so both can take off the anticipation of groove by detecting grooving 2 pressure change, also can accurately detect simultaneously to carry out steel wire rope 5
De- groove or loosens in which root steel wire rope 5, and is easy to detect and safeguards.
Concrete decision logic：
The parameter pre-setting is divided into：Steel wire rope 5 takes off groove anticipation parameter A and B, and steel wire rope 5 has taken off groove parameter C.(wherein join
Number A, B can be scaled according to in-site installation situation.A is smaller value, parameter when steel wire rope 5 loosens；B is higher value, steel
Cord 5 soon takes off groove, parameter during compressing main wheel/car wheel edge)
Assume that the pressure data that a certain grooving of device 2 transmits is X, work as C<X<A or X>During B, output steel wire rope 5 loosens
To elevator control panel, elevator can continue to run with anticipation signal within a certain period of time, and elevator monitoring equipment can send automatically simultaneously
Elevator wire rope 5 loosens signal to corresponding repair and maintenance personnel, after exceeding certain time, if having also detected that steel wire rope 5 loosens
Signal, then elevator control panel quote respective level fault, elevator forbid run；Work as X<During C, output elevator wire rope 5 takes off groove letter
Number arrive elevator control panel, elevator control panel quotes respective level fault, and elevator is forbidden running, and elevator monitoring equipment is sent out automatically simultaneously
Elevator wire rope 5 is sent to take off groove signal to corresponding repair and maintenance personnel；Work as A<X<During B, then output steel wire rope 5 normal state signal is to electricity
Terraced panel.
C. signal processing unit can layout becomes the binary number of several bytes in order by the status data of each grooving 2
Value, and it is transferred to elevator control panel, wherein every steel wire rope 5 state takies two positions, is 00 when normal, is 01, takes off when loosening
It is 10 during groove.As elevator has eight steel wire ropes 5, the data sending during steel wire rope 5 normal condition is 00 00 00 00 00 00
00 00；When steel cable 5 loosens, send steel wire rope 5 to take off groove anticipation signal data is 00 00 00 00 00 00 00
01；When steel cable 5 takes off groove, send steel wire rope 5 to take off groove signal data is 00 00 00 00 00 00 00 10.
